    ASoC: Intel: Fix RT5650 SSP lookup · 6f6a23d4
    Curtis Malainey authored
    Commit 8efcd486 ("ASoC: Intel: sof_rt5682: use common module for
    sof_card_private initialization") migrated the pin assignment in the
    context struct up to soc-acpi-intel-ssp-common.c. This uses a lookup
    table to see if a device has a amp/codec before assigning the pin. The
    issue here arises when combination parts that serve both (with 2 ports)
    are used.

    kobject: kobject_add_internal failed for SSP0-Codec with -EEXIST, don't try to register things with the same name in the same directory.
    
    The issue is that the ALC5650 was only defined in the codec table and
    not the amp table which left the pin unassigned but the dai link was
    still created by the machine driver.
    
    Also patch the suffix filename code for the topology to prevent double
    suffix names as a result of this change.
